Explain how the terms oxidation and reduction apply even when there is only a partial shift of electrons between atoms linked by
aliina [53]

Explanation:

In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.

Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.

Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.

Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.

Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.

  • Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
  • This leaves a partial negative charge on it.
  • The other electron then becomes partially positively charged.
  • We can then say, the more electronegative specie undergoes reduction.
  • The less electronegative one undergoes oxidation.

Which of the following describes the nervous system integrative function? A. responds to stimuli by gland secretion or muscle co
Verdich [7]

Answer:

B. analyzes sensory information, stores information, makes decisions

Explanation:

The receptors sense the changes or stimuli. The sensory neurons of the nervous system deliver this sensory information to the processing center, that is, to the central nervous system. The central nervous system serves to store the information and analyze it to determine the best suitable response. The ability of the nervous system to the store and process of sensory information to make the effector organs to exhibit the best response represents its integrative function.
